co-rrect.

Also maybe a different seat, to make you more comfortable while riding.

22inch rear tires.

all this stuff will make you quicker. in order to go faster you need to chainge your gearing or raise your rev limiter.

[wilkin250r]

As mentioned already, your next mods should probably be head porting and a bigger carb.


If you want to go even further, you can stroke it, or just balance the crank for the heavier 440 piston. The balance will allow it to rev higher, and then add a high-rev CDI. These additions would compliment head porting and a larger carb very well for dramatic gains in the upper RPMS and increased peak HP.

HAHA Funny;)

[1fst400]

build one of these.

depending on how nice you quad is set up suspention wise. this could be a more cost friendly than selling your quad for a 450r. Plus IMO this is a beter quad.

thats what i'm going to do in a couple of yrs

[honda460ex]

:) Definately stroke it! :D I t Works!!! And up to 13 to 1 compression with a JE, then a stroker cam... :cool:

[mic 902]

Well mine is a 440 and it keeps up with most 450's that are piped and one oe two off the 450's i ride with have aftermarket cams. I got stage 1 hot cam 11:1 piston going to 12.5:1 and some light port work. My carby has had work done to it like taking the choke out and some other things. Going to a 450 carb this rebuild. :)
PS its not stroked.:)

i'll bet that if u stroked it to a 440 instead of bore it, u would be at least keeping up, if not beating heavily modded 450s. i see 426s and 440s beating fully built 450s on the track. it just depends on how it's built.

[Toadz400]

Stroke it and bore it. That way you have the torque of the stroker along with the higher rev capabilities of the normal bore. Get that bigger carb on there and a different cam, look into a stage 2 or stage 3.

Also suspension is going to help you a lot if you're riding tracks or woods.

CRF Motor....




I'll sell ya one!
If you keep the EX motor, I'd do port and polish and bigger carb for sure.

[SLSD400exGUY]

:huh :huh :huh


O yeah, that works well with a modified exhaust bearing and a green powerband!

[pimpinyfz450]

hey man no offense or anything but if your gonna do all that work to it then y not just get a 450 and then youll kill it and your motor will b stock .......the quad does sound nice though

[SLSD400exGUY]

i want to be different.. :o)

[firefighterjosh]

I have never owned a Elderbrock carb, but from what I hear they are very very hard to tune.

[SLSD400exGUY]

ive heard that too... not sure yet ill have to see what goes on

[krt400ex]

being diff. is cool

I'd reccomend the Keihin FCR-MX carb opposed to the Eddelbrock.
